Phone with good SQ?

I'm looking to get a new (used, I don't have a contract) phone, obviously SQ is important to me. Which phones have good audio that can be bought used for a decent amount. I'd like to keep it ~200 but I would be willing to stretch that if it's worth it (i.e. current generation smartphone).

For reference, I have an ipod 5.5g. I understand most phones aren't that good, but I'd like something at least comparable to the ipod. I would be very happy with anything at least as good as my ipod.
